Many people talk about "social justice" as if it's separate from Christian faith, or even opposed to it.
There are worldly people who try to set up their own way of justice. This indeed is separate from Christianity . . . meaning how the Bible represents that Christianity is to be.
Yes, Jesus did good to people. Please note how Jesus did good in personal sharing and communication with people. He did not only have programs with controls determined by people who did not even personally know the ones who were being considered for benefits.
You can feed on . . . if you haven't, already . . . how the early church arranged for needy Christians to get assistance >
Acts 6:1-7.
The people selected men who they knew were honorable and reliable and competent, and these men took care of distributing things for the needs of people. The people personally knew the ones they chose for this good work. Plus, I can see how these men personally knew the ones they helped with church resources.
Churches and individuals do this now . . . already . . . as followers of Jesus. So, is this separate from God's way of Christianity? N
So, you can do this, now, as an individual, and find ones who are doing this and join them.
My opinion is that if a group or people are not already doing things to help the needy . . . this could be because they are not with Jesus. So, I would not try to "pull teeth" to get them to do something "social", if they have not started with Jesus. But find people who already are doing good and support them. And, of course, make sure they really are growing in Jesus and relating as His family, as God's word says, while reaching to needy people.
"though I bestow all my goods to feed the poor," "but have not love, it profits me nothing." (in 1 Corinthians 13:3)
There are ones who have done "great" things to help other people, but they were acting from bitterness and were self-righteously criticizing and looking down on others, while doing what they did. They were looking to people to do what *they* dictated should be done, not first submitting to God and obeying how He pleases to use us to help people: personally, most of all.
I now think of this > in the United States we have some number of very well-to-do people > who are "entitled". And they can be on drugs and going on to suicide, because they were not brought up to know how to love. They were fed arguing and complaining and beauty discrimination and anger and unforgivenes and looking down on others and using some preference for pleasure to try to satisfy themselves . . . not learning how to be and how to love like Jesus. So, in case you were to help all needy people to become rich like such selfish wealthy ones . . . they might likewise become selfish and entitled, themselves . . . and gain the world they want and lose their souls.
